Item 6542 Clinical profiles of children less than 5 years presenting with or high risk of cerebral palsy in the Western Province of Sri Lanka(BMJ, 2024) Sumanasena, S.; Heiyanthuduwage, T.M.; Fernando, R.; Sheedy, H.S.; Jagoda, J.; Wijesekara, S.; Wanigasinghe, J.; Muttiah, N.; Rathnayake, P.; Kitnasamy, G.; Khandaker, G.OBJECTIVES Cerebral palsy (CP) is the commonest physical disability in children globally.1 It is a clinical diagnosis based on clinical and neurological findings. International clinical practice guidelines recommend early diagnosis and CP specific interventions to invest in neural plasticity and achieve optimal functional levels.2 In the past diagnosis was confirmed at 12–24 months but now it is advanced to confirm or identify as high risk for CP before the age of six months.3 4 Sri Lanka is one of the few Asian countries that initiated a CP register and National Guidelines on management of CP.5 The objective of this paper is to describe the clinical profiles of children less than 5 years presenting to Western Province hospitals in Sri Lanka based on the data from the Sri Lanka Cerebral Palsy Register (SLCPR).METHODS A cross sectional hospital-based study was conducted in the Western Province from September 2018 – October 2021 in three teaching hospitals to collect a minimum data set for the Sri Lanka SLCPR. Data of children less than 60 months was extracted with a confirmed clinical diagnosis of CP or identified formally as ‘high risk’ of CP.Information on sociodemographic, pre/peri/neonatal, and post neonatal risk factors, and associated impairments were collected using hospital records and clinic notes. Clinical motor type, topography, and associated impairments were evaluated.RESULTS Data of 431 children were extracted, 254 (58.9%) were males. Mean age at diagnosis was 28.73 months (median 27, SD 14.98). Most children (n= 422, 97.9%) acquired CP in the pre/peri/neonatal period. The mean birth weight was 2304.4 g (median 37, SD 825.58g) and the mean POA was 35.82 months (median 37, SD 4.88). Main risk factors identified were prematurity (n=190, 44.1%), hypoxic ischaemic encephalopathy (HIE) (n= 234, 54.3%), jaundice (n=31, 7.2%) and sepsis (n= 13, 3.0%). While 183 children (42.5%) showed evidence of definitive spastic motor type, 184 (42.7%) showed predominant dyskinesia.CONCLUSION The age at diagnosis of this population from Sri Lanka is significantly lower than from other LMICs. HIE and prematurity, both preventable conditions remain the highest risk factors. Longitudinal follow up will ascertain the final motor outcomes as a higher proportion of children showed dyskinesia. The SLCPR is an important resource which will support new research towards investigating opportunities for prevention and service planning for children.Item 6503 Using anthropometric data to investigate the nutritional status of children included on the Sri Lankan cerebral palsy register.(BMJ Publishing Group Ltd, 2024) Sumanasena, S.; Fernando, R.; Kurukulaarachchi, S.; Heiyanthuduwage, T.M.; Sheedy, H.S.; Wijesekara, S.; Jagoda, J.; Muttiah, N.OBJECTIVES The nutritional data from children with cerebral palsy (CP) in low and middle income countries (LMIC) is sparse. In high income countries (HICs) well established nutritional care plans, commercial products and good psycho-social support are available.1 A multitude of complications arise due to malnutrition leading to poor quality of life.2 Here we investigated the nutritional status of children included in the Sri Lankan Cerebral Palsy Register (SLCPR).METHODS The study included 768 children aged 0–18 years with CP, attending three teaching hospitals in the Western Province, from September 2018 to November 2021. Data included clinical profile and anthropometry [weight (Kg), height (cm), BMI, mid upper arm circumference (MUAC) (cm), and OFC (cm)] based on WHO. Average was calculated using three repeated measurements. Children who could not stand independently (GMFCS level 4/5) underwent height estimations with the knee height equation: height = (2.69 X Knee height) + 24.2.Indicators used to measure the nutritional status were: weight for age Z score (WAZ), height for age Z score (HAZ), weight for height Z score (WHZ), BMI for age Z score (BAZ), and MUAC for age Z score (MUACZ). WHO Anthro and WHO AnthroPlus software calculated all Z scores.4 HAZ and BAZ were calculated for children aged <18 years, WAZ was calculated for children aged <10.1 years, and WHZ and MUACZ were calculated for children aged <5.1 years. The z scores < -2.0 SD were categorized as underweight (WAZ), stunted (HAZ), wasted (WHZ or MUAC), thin (BAZ).RESULTS Total of 768 children (mean age 59.6 months, SD 44.9, 62.5% males) participated. There were (n=431) children under 61 months and (n=520) from 0–10 years. Of them, 51.3% (n = 267/520) were underweight, 59.8% (n = 258/431) were stunted and 27.3% (n = 210/768) were thin. Among children aged < 5 years, 26.7% (n = 115/431) had severe wasting and severe acute malnutrition (SAM) according to MUACZ < -3SD. Both underweight and stunting were significantly higher among children with spastic CP compared with others (p<0.05). In the 5–19 year group 16.9% (n= 57/337) were obese (BAZ > + 2SD).CONCLUSION Predominant stunting and underweight in this population calls for urgent action to minimize chronic malnutrition. It is imperative to further explore nutritional intake and feeding difficulties in this group and offer structured nutritional care plans. The trend observed in older children towards obesity possibly indicates the need for coordinated nutrition and exercise programmes. It is recommended to regularly monitor growth and nutritional status of all children with CP as there may be serious implications for their activity levels.Item Fish bone migration through a sigmoid colon diverticulum causing an anterior abdominal wall abscess(The College of Surgeons of Sri Lanka, 2024) Ekanayaka, E.M.M.; Gunasekara, K.; Fernando, R.; Chandrasinghe, P.C.; Kumarage, S.No abstract availableItem Improving psychological well-being among healthcare workers during the COVID-19 pandemic with an online mindfulness intervention: A randomised waitlist-controlled trial(Wiley, 2024) Baminiwatta, A.; Fernando, R.; Solangaarachchi, I.; Abayabandara-Herath, T.; Wickremasinghe, A.R.; Hapangama, A.The high prevalence of psychological problems observed among healthcare workers (HCWs) during the COVID-19 pandemic called for interventions to safeguard their mental health. We assessed the effectiveness of a 6-week online mindfulness-based intervention in improving well-being and reducing stress among HCWs in Sri Lanka. Eighty HCWs were recruited and randomised into two groups: waitlist-control (WLC) and intervention groups. In the intervention, 1-hour online sessions were conducted at weekly intervals and participants were encouraged to do daily home practice. Stress and well-being were measured pre- and post-intervention using the Perceived Stress Scale and WHO-5 Well-being Index, respectively. One-way analysis of covariance was used to evaluate the effectiveness, in both intention-to-treat (ITT) and complete-case (CC) analyses. A significantly greater improvement in well-being occurred in the intervention arm compared to WLC on both ITT (p = .002) and CC analyses (p < .001), with medium-to-large effect sizes (partial η2 = .117-.278). However, the reduction in stress following the intervention was not significant compared to the WLC group on both ITT (p = .636) and CC analyses (p = .262). In the intervention arm, the median number of sessions attended by participants was 3. Low adherence to the intervention may have contributed to the apparent non-significant effect on stress.Item Trials, tribulations and the emergence of total thyroidectomy - A Sri Lankan perspective(The College of Surgeons of Sri Lanka, 2023) Fernando, R.Abstract The technique of thyroidectomy has emerged during the last 100 years, from a turbulent past’, due to the outstanding contributions made by many including the “Magnificent Seven” of thyroid surgery. The dissection of the gland, preservation Parathyroid function and protecting the Nerves are dealt with meticulously. Total thyroidectomy is associated with complications of bleeding, permanent injury to Nerves and permanent hypoparathyroidism. Many centres have reported incidence of complications around 1-3%. This is the bench mark for surgeons world over. Voice change is a major concern after thyroidectomy. A study has shown that RLN recovery much faster than the recovery of the EBSLN. The recovery will take up to 3 months in most patients. Assessment of the surgical practices related to thyroid disease in Sri Lanka has shown that the practices have changed over the last decade. More total thyroidectomies are undertaken. Younger surgeons are undertaking more total thyroidectomies. The quoted incidence of Incidental carcinoma is around 10-20% in the literature. In two studies done in the unit, an incidence between 8.8% and 11.38% was seen. This factor must be considered in surgical decision making for benign disease. Most common cause of recurrences is the enlargement of embryological remnants of the thyroid and a modern thyroid surgeon must excise the embryological remnants meticulously. Surgery for recurrent goitre is a difficult task. Data confirms that Lateral approach to the thyroid makes the task much easier. This must be considered a bench for Sri Lanka. Cosmetic issues and cost must also be considered in thyroidectomy. Data confirms that Mini incision open thyroidectomy is a safe cost effective alternative to endoscopic thyroidectomy The obituary of open total thyroidectomy shall not be written for a long time.Item Assessing motivation to lose weight: the psychometric properties of the Sinhala version of University of Rhode Island Change Assessment (URICA) scale(Sri Lanka Medical Association, 2023) Niriella, M.A.; de Silva, S.T.; Hapangama, A.; Baminiwatta, A.; Fernando, R.; Ediriweera, D.INTRODUCTION: Weight reduction through lifestyle modifications is an important component in the management of various chronic diseases. The degree of motivation to change has been shown to predict outcomes in weight reduction interventions. Thus, the availability of a validated self-report tool assessing the degree of motivation for weight management would be useful for both clinical and research purposes in Sri Lanka. OBJECTIVES: To examine the structural validity and internal consistency of the URICA for weight management in a sample of Sri Lankan adults with chronic medical conditions. METHODS: Standard procedures for cross-cultural adaptation of a questionnaire were followed in translating the 32-item URICA into Sinhala. The Sinhala version was administered to 208 patients aged 18-60 years attending outpatient clinical services for non-disabling chronic medical diseases. Psychometric testing included confirmatory factor analysis and the assessment of internal consistency (Cronbach α). RESULTS: The commonly accepted four-factor structure of URICA reflecting Prochaska and Di Clemente’s transtheoretical model (pre-contemplation, contemplation, action and maintenance) showed good model fit, after the removal of four items from the pre-contemplation subscale due to inadequate factor loadings (<0.4). In line with theory, factor correlations indicated that the pre-contemplation factor was inversely correlated with the other three factors, while the other three factors were positively correlated with one another. All four subscales showed good internal consistency (Cronbach α ranging from 0.73 to 0.89). CONCLUSIONS: The Sinhala version of a modified 28-item URICA was found to have sound psychometric properties as a measure of motivation for weight management among Sinhala-speaking adult patient.Item Identification of type 2 diabetes patients with non-alcoholic fatty liver disease who are at increased risk of significant hepatic fibrosis: a cross-sectional study(Sri Lanka Medical Association, 2023) Mettananda, K.C.D.; Egodage, T.; Dantanarayana, C.; Solangarachchi, M.B.; Fernando, R.; Ranaweera, L.; Siriwardhena, S.; Ranawaka, C.K.; Kottahachchi, D.; Pathmeswaran, A.; Dassanayake, A.S.; de Silva, H.J.INTRODUCTION: Annual screening of patients with diabetes for fatty liver, and identifying those with significant hepatic fibrosis using the FIB-4 score and vibration-controlled transient elastography (VCTE) has been recommended to detect patients who may progress to advanced hepatic fibrosis/cirrhosis. However, VCTE is not freely available in resource-limited settings. OBJECTIVES: To identify clinical and biochemical predictors of significant liver fibrosis in diabetics with fatty liver. METHODS: We conducted a cross-sectional study among all consenting adults with T2DM and non-alcoholic fatty liver disease (NAFLD) attending the Colombo North Teaching Hospital, Ragama, Sri Lanka from November 2021 to November 2022. FIB-4 scores were calculated and patients with a score ≥1.3 underwent VCTE. Risk associations for liver fibrosis were identified by comparing patients with significant fibrosis (LSM ≥8 kPa) with those without significant fibrosis (FIB-4<1.3). RESULTS: A total of 363 persons were investigated. Of these, 243 had a score of FIB-4 <1.3. Of the 120 with a FIB-4 ≥1.3, 76 had LSM ≥8 kPa. Significant fibrosis was individually associated with age (OR 1.01, p<0.0001), duration of diabetes (OR 1.02, p=0.006), family history of liver disease (OR 1.42, p=0.035), waist (OR 1.04, p=0.035), and FIB-4 (OR 2.08, p<0.0001). However, on adjusted analysis, significant fibrosis was only associated with a family history of liver disease (OR 2.69, p=0.044) and FIB-4 (OR 1.43, p<0.001). CONCLUSION: In patients with T2DM and fatty liver, advancing age, increased duration of diabetes, a family history of liver disease, waist circumference and a high FIB-4 score increase the risk of significant hepatic fibrosis. Targeted interventions in this group may help prevent progression to advanced hepatic fibrosis/cirrhosis.Item Measuring resilience among Sri Lankan healthcare workers: validation of the brief resilience scale in Sinhalese and Tamil languages(Sage Publishing, 2023) Baminiwatta, A.; Fernando, R.; Gadambanathan, T.; Jiyatha, F.; Sasala, R.; Kuruppuarachchi, L.; Wickremasinghe, R.; Hapangama, A.Resilience is the capacity for adaptation and “bouncing back” in the face of adversity.1,2 It protects against mental health problems such as depression, anxiety, and stress and improves well-being. 3 During the COVID-19 pandemic, there was a growing need for studies on protective factors in mental health, such as resilience, particularly among healthcare workers. 4 Psychometric assessment of resilience is a prerequisite for research in this area. A review of 19 resilience scales found a wide variation in their psychometric properties, with all of them posing some challenges. 5 However, the authors noted that the Resilience Scale for Adults, Brief Resilience Scale (BRS), and the Connor-Davidson Resilience Scale had the finest psychometric ratings. BRS may have an exceptional place in behavioral research because other resilience scales tend to assess resources that promote resilience rather than resilience itself. BRS is probably the only measure to assess resilience in its most basic meaning—the ability to “bounce back.” 2 Furthermore, among resilience scales, BRS is short and, therefore, would generate better response rates in research. As BRS was not available in local languages, its validation into Sinhalese and Tamil languages was needed to enable research on resilience in Sri Lanka. METHODS: Approval was obtained from the Ethics Review Committee. The procedure for questionnaire translation followed the recommendations of Beaton et al. (2000). 6 Firstly, BRS was translated into each local language (Sinhalese and Tamil) independently by two bilingual experts, and a consensus translation was prepared. The translated version was back-translated into English by two independent bilingual translators. They were compared with the original BRS for semantic, idiomatic, experiential, and conceptual equivalence by a group of experts comprising several Sinhalese- and Tamil-speaking psychiatrists, bilingual experts, and a methodologist. A few phrases in the original English version, such as “bounce back” and “snap back,” were replaced with conceptually equivalent phrases in the local languages. Face and content validity were discussed, and a consensus translation was prepared. After conducting a pre-test and cognitive debriefing with a purposive sample of 10 healthcare workers for each language, and further minor modifications, the translated scales were administered to 150 Sinhalese- and 110 Tamil-speaking healthcare workers (nurses, doctors, and other categories), after obtaining informed consent (see Table S1 for the sociodemographic profiles; the translated questionnaires are provided as supplementary files). Confirmatory factor analysis (CFA) was used to test the model fit for the one-factor structure of BRS, 2 using the following fit indices: comparative fit index (CFI), Tucker Lewis index (TLI), standardized root mean square residual (SRMR), and root mean square error of approximation (RMSEA). Depression, anxiety, and Stress Scale -21 (DASS-21) was administered to test expected inverse correlations with resilience. RESULTS: According to CFA, the six-item BRS formed a unitary construct, with satisfactory model fit for both the Sinhalese (CFI = 0.99, TLI = 0.99, RMSEA = 0.09, SRMR = 0.05) and Tamil versions (CFI = 0.98, TLI = 0.97, RMSEA = 0.14, SRMR = 0.07). Factor loadings of individual items ranged from 0.59 to 0.86 in the Sinhalese and 0.61 to 0.82 in the Tamil version (see Table S2 for item-level statistics). Cronbach alpha of the Sinhalese and Tamil BRS were 0.82 and 0.80, respectively, indicating good internal consistency. Removal of any single item did not significantly improve internal consistency. The Sinhalese BRS score had significant negative correlation with depression (r = –0.29, P = 0.002), anxiety (r = –0.27, P = 0.005), and stress (r = –0.20, P = 0.033), whereas the Tamil BRS score had significant negative correlation with anxiety (r = –0.18, P = 0.028) and stress (r = –0.25, P = 0.002) but not with depression. DISCUSSION: Our findings support the construct validity and internal reliability of the BRS as a measure of resilience. The one-factor structure proposed by the original developers 2 and replicated in subsequent studies 7 was observed in the present study. BRS has been previously translated and validated in several languages, including German, Polish, Spanish and Dutch.7–10 Similar to the observations in the original validation sample 2 and the Spanish validation, 7 resilience, as measured using BRS, showed significant inverse correlations with depression, anxiety, and stress in the present analysis. This provided further support for its construct validity through hypothesis testing. The absence of a significant inverse correlation of the Tamil BRS score with depression may be due to the comparatively small sample size available for the Tamil validation. Although our findings were based on healthcare workers, we expect the scale’s validity to extend to the general population. Thus, the Sinhalese and Tamil BRS can be used in future large-scale research on resilience in Sri Lanka. As high rates of mental health issues were reported among healthcare workers in Sri Lanka during the COVID-19 pandemic, 11 and the country is currently going through an unprecedented economic crisis, it is important to take measures to enhance resilience among Sri Lankan healthcare workers. The availability of a validated tool in both Sinhalese and Tamil languages would enable research on mental health and resilience among culturally-diverse populations in Sri Lanka, which would provide useful information to guide health policy development. Limitations of this study include the small sample sizes and the lack of test-retest reliability assessments to ascertain the temporal stability of the BRS scores.Item Improving medical students' understanding of dementia using a movie ( The Father)(Taylor & Francis, 2023) Baminiwatta, A.; Fernando, R.; Williams, S.No abstract availableItem Identification of patients with type 2 diabetes with non-alcoholic fatty liver disease who are at increased risk of progressing to advanced fibrosis: a cross-sectional study(BMJ Publishing Group Ltd, 2023) Mettananda, C.; Egodage, T.; Dantanarayana, C.; Fernando, R.; Ranaweera, L.; Luke, N.; Ranawaka, C.; Kottahachchi, D.; Pathmeswaran, A.; de Silva, H.J.; Dassanayake, A.S.INTRODUCTION: Identification of advanced hepatic fibrosis in non-alcoholic fatty liver disease (NAFLD) is important as this may progress to cirrhosis and hepatocellular carcinoma. The risk of hepatic fibrosis is especially high among patients with diabetes with NAFLD. Annual screening of patients with diabetes for fatty liver and calculation of Fibrosis-4 (FIB-4) score and exclusion of significant fibrosis with vibration-controlled transient elastography (VCTE) have been recommended. However, VCTE is expensive and may not be freely available in resource-limited settings. We aim to identify predictors of significant liver fibrosis who are at increased risk of progression to advanced liver fibrosis and to develop a prediction model to prioritise referral of patients with diabetes and NAFLD for VCTE. METHODS AND ANALYSIS: This cross-sectional study is conducted among all consenting adults with type 2 diabetes mellitus with NAFLD at the Colombo North Teaching Hospital, Ragama, Sri Lanka. All patients get the FIB-4 score calculated. Those with FIB-4 ≥1.3 undergo VCTE (with FibroScan by Echosens). Risk associations for progression to advanced liver fibrosis/cirrhosis will be identified by comparing patients with significant fibrosis (liver stiffness measure (LSM) ≥8 kPa) and without significant fibrosis (LSM <8 kPa). A model to predict significant liver fibrosis will be developed using logistic regression. ETHICS AND DISSEMINATION: Ethical approval has been obtained from the Ethics Committee of the Faculty of Medicine, University of Kelaniya (P/66/07/2021). Results of the study will be disseminated as scientific publications in reputable journals.
